Malin Akerman and her ex-husband Roberto Zincone split up just four months after she gave birth to their son Sebastian and now her new Sin City Saints co-star Tom Arnold is slamming him for the failed marriage.

“She’s a single mom. Her deal — and I probably shouldn’t talk about her — but…I have so much respect for her. She is such an amazing woman,” Tom said on The Howard Stern Show on Tuesday (January 13).

“You know, her husband, they’re together 10 years, they have a baby, [and] four months in, he’s like, ‘I’m done,’” Tom added (via Us Weekly). “So she not only pays him alimony to take care of this guy, but I watched her as a mother, and I was like, ‘This is the most inspiring woman. I’m not gonna complain about anything in my life.’ Because she is incredible. She is an inspiration.”
